Description:

The search to improve and lower costs of manufacturing parts of the automotive
industry results in the present study, which has the title "Influence of the pressure
of forming and sequence of lamination in layers on the resistance to bending
and impact of a composite of polyester matrix and reinforced with glasscarbon
fiber ", in which the sequence of lamination of the glass fiber and carbon
layers is taken as the study variables in the following way; 4V, 3V + 1C, 2V + 2C,
1V + 3 and 4C, as well as the second variable of the study the compounding pressure
of the compounds is varied. To study the mechanical properties of these
compounds, impact and bending tests were carried out according to UNE-ISO 179-
1 and ASTM D 7264D, 2007 standards respectively, in which the dimensions of the
test specimens are indicated.
From the results obtained, the maximum resistance to impact was 160.67 KJ / m2,
corresponding to the compound formed with 4 layers of carbon fiber and with a
pressure of 2500 PSI and for the composite formed with 4 glass fibers and a pressure
of 1500 PSI the resistance minimum was 71.91 KJ / m2, there being a difference of
55.24% between both values. In the same way, the maximum flexural strength of
compounds formed with 4 layers of carbon fiber was found with 2500 PSI, which
was 208.39 MPa and the minimum value of flexural strength is 145.84 MPa, with
a difference of 30.01%, likewise in both tests was found fault by delamination and
detachment of fibers, the latter case in greater evidence in composites formed a
pressure of 1500 Psi, this because of the lack of adherence
